The main purpose is to see whether the light decay of the LED lamp is actually damaged during the assembly process, and check again whether the power supply is stable in a high temperature environment, and a short aging time The light efficiency cannot be evaluated. The aging test has flexibility in actual operation, which can not only meet the requirements of relevant standards, but also improve production efficiency.</p>

<p>At present, most of the industry tests are carried out according to the aging time of 1000 hours, and the light decay of different brand manufacturers is different. The LED working life test mainly passes:</p>
<p>Test Room Temperature Operating Life (RTOL)</p>
<p>High Temperature Operating Life Test (HTOL)</p>
<p>Wet High Temperature Operating Life Test (WHTOL)</p>
<p>Low Temperature Operating Life Test (LTOL)</p>

In practical applications, the luminous efficacy of finished LED lamps is lower than that of simple high-power light-emitting diodes. Due to the influence of power drive, heat dissipation, lens, etc. The higher the light efficiency, the better.</p>
<p>There is no standard for light decay, the industry internal standard is:</p>
<p>1000 hours light decay is 0.</p>
<p>3000 hours light attenuation is 1%</p>
<p>10000 hours light attenuation is 3%.</p>
<p>No more than 30% of 50,000 hours.</p>
<p>Generally, the manufacturers that can achieve the above-mentioned light decay are relatively regular manufacturers. The chips used by many manufacturers outside are not very good. If you want to buy a good LED, it is recommended that you go to the new sunshine LED lighting company to buy</p>
<p>The standard can refer to the US Energy Star LM-80 standard.</p>
